Solid state and solution structures of dimeric organolithium derivatives of a P2N4S2 ring
An X-ray structural determination of the dimer [Li(Ph4P2N4S2Ph)-THFl2 (THF = tetrahydrofuran) reveals a step-shaped structure; 7Li and 31P NMR investigations of [Li(Ph4P2N4S2R)-THFl2 (R = Me, But, Ph), as a function of temperature and concentration, in THF solution show that this dimer is fluxional and indicate the presence of a second dimeric species.
